Someone requested this on the Folk North West website some time ago and I got the following words from someone:

Picking All The Big Ones Out

As i was going home to tea
I thought I'd have a luxury
So off i went to mother macspinkles,
Bought myself a pennyworth of winkles

Went back home and put 'em on a plate as happy as can be
And then i went upstairs while all the fa-mi-ly ...
Were picking all the big ones out
Picking all the big ones out

D'y'ever see a man's face so full of wrinkles
As when i saw my pennyworth of winkles
All the big ones gone it made me rage and shout
To see the missis and the seven little nippers all
Picking all the big ones out

Don't know if there's any more of this or what the tune is.

Cheers
Mark
